problems modifing the Torque engine... any ideas?

I have the pro version of Torque3D and can modify the code in the engine, however in my game project I can't access the new variables and methods I added to the Torque engine.

Any ideas? I've tried building, rebuilding, cleaning, closing and reopening etc but visual studio just can't see the new functionality. I've included the relevant references of course (using GarageGame.Torque.T3D;)
